Tacna, the last city in southern Peru on the border with Chile, is the new scene of the migratory drama.
Groups of migrants seeking to cross the border have accumulated there in recent weeks and have met the Army.
Faced with the growing desperation of entire families waiting in the arid conditions of the Atacama desert, there have been clashes and protests against the security forces that guard the site.
Last week, the Government of Peru ordered a state of emergency in the area with elements of the Army deployed to maintain the limits.
This decision imitated the one taken by Chile weeks before.
The crisis has been aggravated by the growing number of Venezuelans who decide to return to their country and find their doors closed.
Since the murder of a Chilean police officer on April 5 at the hands of two Venezuelans, the rest of the nationals have experienced increasing discrimination against them.
Disappointed, they have opted to re-enter their homeland, but to do so, they must first clear border security or venture into the desert on their own.
This Sunday, a first humanitarian flight was launched, coordinated by the Chilean Foreign Ministry with the Government of Nicolás Maduro, in which hundreds of Venezuelan migrants are expected to return to their country.
The plane left for Caracas from the border city of Arica, 2,000 kilometers north of Santiago.
